* Continued work on the new LLUDP implementation. Appears to be functioning, although not everything is reimplemented yet
* Replaced logic in ThreadTracker with a call to System.Diagnostics that does the same thing
* Added Util.StringToBytes256() and Util.StringToBytes1024() to clamp output at byte[256] and byte[1024], respectively
* Fixed formatting for a MySQLAssetData error logging line
